The present project focus on two aspects of the study of how elliptical galaxies evolve in different environments and as a function of the redshift: 1) Constraining, with unprecedented detail, the stellar IMF of massive, nearby, early-type galaxies, using new, extremely deep, proprietary spectroscopy obtained from the proposers with the VLT X-Shooter spectrograph; 2) Application of an alg…
Constraining almost 14 billion years of galaxy evolution from observations of galaxies as they are seen today is fraught with peril. Here we propose a program to extend galaxy evolution studies to infrared wavelengths and higher redshifts (larger lookback times) to consistently investigate galaxies and their environments over a significant time baseline. A major step will be the implement…
The goal of the present project is to engineering 2DPHOT, complementing the package with the required tools to process the large photometric data-sets provided by current and next-generation wide-field surveys. Specifically, we plan to fulfill the following tasks: bulge/disk decomposition; PSF modelling and database modeling for the SDSS and UKIDSS data being processed. During the visit w…

We propose to study the astrophysical properties of galaxies that host Gravitational Wave (GW) events to determine if there are preferential environments for these phenomena. We will focus on neutron star mergers, which produce short Gamma-Ray Burst (sGRB) emission in addition to gravitational radiation. Our initial galaxy sample comprises 37 sGRB hosts, one of which is also a GW host can…
This project is focused on understanding how environmental mechanisms rule galaxy evolution, especially in galaxy clusters. Ram pressure stripping and starvation are pointed out as the main mechanism for star formation quenching in galaxies. However, other effects, such as tidal mass loss and galaxy-galaxy merger, may also play a fundamental role in shaping galaxy evolution. We aim to com…
We intend to study different methods of analysis of the velocity distribution of galaxies in clusters aiming to establish how Gaussian the distribution is and its reliability. We will be studying the catalog of groups and clusters defined in Yang et al. 2007 (ApJ, 671, 153). The properties of galaxies in these systems are available in the SDSS-DR7. In this project, we will also study the …
The way galaxies form and evolve throughout the cosmic time remains one of the greatest challenges of modern cosmology. Galaxy formation involves many different physical mechanisms that leave typical imprints in the luminous matter. Therefore, the stellar content of galaxies can provide a wealth of information on how these systems were assembled. In this project, we propose to study stell…
This project is focused on understanding how environmental mechanisms rule galaxy evolution, especially for central galaxies. We will use the observations from the Sloan Digital Sky Survey (SDSS) combined with galaxy classification from the Yang Catalog to investigate how central galaxy properties depend on different parameters, such as: host halo mass, stellar mass, number of satellite g…
